# Geometry

Geometry is about more than just drawing lines and shapes. It’s about exploring the relationships between objects in space, solving multi-step problems, and writing proofs. But don’t let that intimidate you. In my free geometry lessons, we’ll break everything down from calculating the area and volume of shapes to measuring angles, understanding conditional statements, and of course, mastering the Pythagorean theorem.
